Background technology LED (light emitting diode) light source is the clean energy-conserving light source of green non-pollution, and its accessible luminous flux design objective is rising year by year.Led light source is mainly used on the colour changing light product of some small-powers, low side at present.
High-power light of stage light source mainly adopts golden halogen discharging bulb.Gold halogen discharging bulb is a white light source, and service life is lower, is generally hundreds of and hour does not wait by thousands of hours.Because of the luminous spectrum of golden halogen discharging bulb is white continuous spectrum, the required different color of light of stage can only be by the colored filter realization that filters, and the pattern that makes light project has lower color saturation, and color is neither bright-coloured, and is also abundant.In order to improve monochromatic color saturation, can filter by the extremely narrow optical filter of utilized bandwidth, its weak point is to reduce monochromatic brightness.
If light of stage adopts led light source, then can save described colored filter, and change the color of light source by the electric current of regulating different base colors LED, thus utilize the higher color saturation of monochromatic LED, the performance free degree of light of stage color is greatly improved.But at present the LED caloric value is big, and luminous efficiency is high not enough, and single led chip can not bear high power, and therefore the high light flux of high-power light of stage often will be realized by led array.
